The fire started on 2 September 2016 in Telões, Portugal, and satellites saw it burning for 6 days. Copernicus mapped a burnt perimeter of 866 hectares from satellite imagery, spread across 4 freguesias. According to ICNF, the largest of the 2 recorded fires was detected on 5 September 2016 at 10:48 and declared extinguished on 8 September 2016.
It is the 6th largest in Vila Pouca de Aguiar since 2016 (of 10 with a page). Number 38 in Portugal in 2016, of 180.
Perimeter published by EFFIS (Copernicus).
ICNF: 890 ha (matched records: 2). Difference between the page and the official record: −2.6%. Matched on 8 November 2026.
2 Sept 2016 to 7 Sept 2016: first and last day with fire on the page.
ICNF declared the fire extinguished on 8 September 2016. Satellites may still see smouldering spots afterwards.
Alert according to ICNF: 5 September 2016 at 10:48. Official cause: arson · negligence.
First day with fire on the page (satellite or perimeter): 2 September 2016.
VIIRS detections at 375 m. Most intense hotspot: 123 MW.
There is no official record to compare with. Each hotspot is a pixel detected in one satellite pass, not a separate fire.
Total radiative power on 6 September 2016; hotspots that day: 22.
Fire radiative power (FRP) measures the energy the fire gives off when the satellite passes. Added up by day, it compares intensity, not area.
Fire Weather Index (Canadian system) computed by WorldFires for the day the fire started. Consecutive days without rain before: 6.
This is an index computed from weather model data, not a measurement of the fire nor an official warning. Danger warnings are issued by each country’s authority. Emergency number and official warnings
High of 32.7 °C and minimum humidity of 22% on 6 September 2016; gusts of 49 km/h on 6 September 2016.
These are model values for a cell of about 25 km, not from a weather station: they may differ from what was measured on the ground.
This page’s change log has been kept since 24 October 2026: every night what it publishes is compared and the difference is logged. Anything earlier is reconstructed from each source’s date and marked as reconstructed.
Every night a snapshot of what the page shows is saved. If anything changes, it appears in the list as a log entry.
A version keeps the area, dates, name and official record; the area as it was logged (changes under 2% are not logged). The map, hotspots and weather always show today’s data.

It had gone 6 days without rain (1 mm or more) when it started. Rain came after the fire: 23.2 mm on 13 Sept.

This compares size, not location: both shapes are at the same scale, north up, centred on each other.
Burnt area inside each freguesia, from crossing the official perimeter with administrative boundaries. The distance runs from the point marking the centre of each area to the nearest fire: staying a kilometre away does not mean it reached the houses.
Natura 2000 protected area affected: 100 %
Natura 2000 sites (European Environment Agency, 2024 release) crossed by the perimeter.
Land cover inside the perimeter according to Corine Land Cover, as reported by Copernicus.
According to ICNF, 2 fires started inside this perimeter on these dates, totalling 890 ha (the satellite measured 866 ha).
ICNF records each fire that started at a different time or place separately; the satellite sees a single burned area, so this page groups them together. The numbers on the map show where each one started.
Total according to ICNF: 890 ha, 103 % of the 866 ha in the satellite perimeter.

It started with an FWI of 26.1, a minimum humidity of 33% and 6 days without rain. Fires in the area that started in weather like this since 2016: 37.
First rain (1 mm or more) after it ended: none in the following ten days.

First rain (1 mm or more) after it ended: none in the following ten days.
First rain (1 mm or more) after it ended: 5.3 mm on 20 Aug.
It was 3.6 times larger than the median of its twins and lasted 6 days, against 2 days.
Only 7 of its 37 twins burned more. The weather on the first day does not explain everything: the wind in the following days, the fuel and the firefighting also count. In 15 of 37, not even 1 mm fell in the ten days after the end: they went out without rain. In the rest, the first rainy day brought a median of 4.6 mm.
This is a bank of analogues: it shows what usually happens, not what will happen. With fewer than 15 twins we give no figures. How we calculate it
It was considered over on 7 Sept, and on 13 Sept 23.2 mm fell. We do not know whether the rain or the firefighters put it out. Twins with rain when they ended: 22 of 37, with a median of 4.6 mm.

Drag the line to compare the same ground before the fire and after it.
If the day is cloudy, change the date: each satellite passes once a day. In false colour the burnt ground looks brown or red.
On 7 September 2016 the air beside the fire reached 180 µg/m³ of PM2.5. That day averaged 60: 4.0 times the WHO daily guideline (15).

RSS Changes to this page With cross-checks and a citable version
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.
The perimeter and land cover come from the Copernicus European Forest Fire Information System (EFFIS), measured on MODIS and Sentinel-2 imagery and published under CC BY 4.0. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Freguesia boundaries come from geoBoundaries ADM3 (CC0 1.0 Universal (CC0 1.0) Public Domain Dedication). The area per freguesia is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ slightly from each country’s official figure.
